Basic Clean for Inside Unit

1. Disconnect the unit from all power sources

Follow the manufacturer’s instruction for discharging the capacitor. A capacitor is a device that holds an extra charge to help kick-start the AC motor, so this step is critical to ensure that there is no electrical charge left in the unit before you begin cleaning.

 

2. Clean the outside cover

Wipe down the outside of the unit with a wet cloth. Be sure to get as much dust and grime off as possible so that it doesn’t fall inside the unit when you open the cover.

 

3. Open the front cover

Most covers open off easily with your hands. Other covers may have plastic hooks or screws that need to be removed. Place any screws or clamps in a safe place while you work. 

 

4. If your unit has a reusable filter, it needs to be cleaned

Remove the filter from the AC unit. Place the filter in a bucket, sink or bathtub, filled with warm, soapy water. Swish the filter around to wash off any dirt or buildup, using a soft brush if really dirty.

Allow it to dry completely before returning it to the AC unit. A wet filter will attract extra dirt and mould!

 

5. If your unit has a disposable filter, change it regularly

The manufacturers suggest that filters be changed once a month during the cooling season.

 

6. Vacuum the inside of the unit

Use a vacuum to clean the bottom and sides of the unit, the back of the front cover, and the metal grill (if you have one). If there is lot of dirt, you can also use a moist rag as well.

 

7. Reassemble the unit

Allow the unit to completely dry before reassembling. Plug in the power source and turn it on. Clean up any debris that may shoot out when the unit is powered on again.

8.  Clean the coils: Proceed with CAUTION, otherwise call for a service

Be gentle as you perform these steps. The coils and fan blades are delicate and easy to bend accidentally. Put on your rubber gloves and protective goggles. Add your coil cleaning solution to your water bottle. Lightly spray the coils, and only the coils, with the solution and allow it to sit for about 10-15 minutes. Then, gently pour warm water over the coils. Make sure all coil cleaner is removed. Note: Avoid getting water on any electrical parts near the coils.

Consider placing a dry rag over any electrical parts to avoid water damage.

 

9. Clean the fan blades: CAUTION 

Use a soft, clean cloth to wipe off any dirt on the fan blades.

Wipe gently to avoid bending the blades. A bent blade will make your AC unit even louder!

 

10. Comb the fins of the coils: CAUTION 

Use a fin comb to repair any dents in the fins of your coils.
